Described wheel hub comprises a tubular structure, and described bearing fixing is in described tubular structure, and the internal diameter of described tubular structure and described bearing joint is less than the external diameter of described bearing.
By above design, described bearing firmly is stuck in the described tubular structure, is difficult for rocking.
When described tubular structure of the present utility model is connected with described bearing, adopt principle of expanding with heat and contracting with cold, earlier described belt wheel main body is heated, the internal diameter of tubular structure for the treatment of described belt wheel main body is by after adding thermal enlargement, in described tubular structure, imbed described bearing, allow described belt wheel main body natural cooling then.After treating described belt wheel main body cooling, the internal diameter of described tubular structure almost or fully returns to original size, and like this, described tubular structure just well compresses described bearing, and described bearing and described tubular structure are fitted tightly, and is difficult for rocking, dropping.
The parts of described belt wheel main body are by the rotary pressure technology manufacturing.Select rotary pressure technology for use, make described belt wheel main body, light in structure, material saving, rotary inertia is little.And the manufacturing efficiency height of rotary pressure technology (2～4 of per minute processing), balance quality is good, generally need not Balance Treatment.Select for use rotary pressure technology to make the parts of described belt wheel main body not cave in addition, compact structure, dimensional accuracy height, when combination, each parts can better fit tightly.
The left side of described PATENT left side via structure is provided with a recessed circle, and described recessed circle is provided with an elasticity and jumps circle.The external diameter of described recessed circle is jumped the internal diameter of circle less than described elasticity.Described elasticity is jumped circle and is fitted tightly on described recessed circle.Jump circle by described left elasticity and be arranged on the recessed circle of described PATENT left side via structure, make described bearing and described PATENT left side via structure more fit, more fastening.
The right side of described right side through-hole structure is provided with a recessed circle, and described recessed circle is provided with an elasticity and jumps circle, and the external diameter of described recessed circle is jumped the internal diameter of circle less than described elasticity.Described elasticity is jumped circle and is fitted tightly on described recessed circle.Jump circle by described elasticity and be arranged on the recessed circle of described right side through-hole structure, make described bearing and described right side through-hole structure more fit, more fastening.
Described left side wheel body is provided with at least one through hole, and described right side wheel body is provided with at least one through hole, can save material, weight reduction like this.Described left side wheel body is corresponding mutually with the through hole of described right side wheel body.The shape of described through hole can be circular, also can be other shapes.
Beneficial effect: owing to adopted technique scheme, the utility model belt wheel main body is connected closely with bearing, is difficult for rocking, and makes to the utlity model has advantages such as safe and reliable, simple in structure, that stability is stronger.
